EC Augmented 3D Location

Class Name: EC Augmented 3D Location

Superclass - <Location 3D>

Subclasses

This DRM class is concrete and has no subclasses.

Definition

An instance of this DRM class specifies a 3D coordinate for an SRF based on the Equidistant Cylindrical SRFT.

See 8.5.24 Equidistant cylindrical SRFT of ISO/IEC 18026 for a complete definition.

Example

  1. Consider a transmittal that contains an <Environment Root> instance R, the ORM of which is SRM_ORMCOD_MULTIGEN_FLAT_EARTH_1989, so that the srf_context_info field of R is specified in an SRF derived from the Equidistant Cylindrical SRFT. An <EC Augmented 3D Location> instance within this SRF might have coordinate field values of easting = 30.0, northing = 50.0, ellipsoidal_height = 100.0.
